ROTARY ENGINE.

SPECIFICATION forming part of Letters Patent No. 642,644, dated February 6, 1900.

Application filed J' 1111c 21, 1897. Serial No. 641,703. (No model.)

spaces oppositely arranged on the interior thereof and mounting a piston within the chamber, so as to form a space on each side thereof. The steam-inlet spaces are in communication With'the spaces on one side of the piston, so that when steam is supplied to the casing it will enter these spaces and operate the piston from a nugnber of points instead of one, as heretofore. The outlet-passages are preferably arranged alternate with the inlet-passages, so that as the pockets contain- .ing live steam pass over them it is exhausted.

In this manner after the greatest force of the steam has been exerted on the piston it is immediately exhausted and not carried around in the casing, as ordinarily, thereby doing away with a great deal ,of resistance.

In order that my invention may be fully understood,I will proceed to describe the same with reference to the following drawings, in which-"- Figure 1 is a perspective view of a rotary engine constructed in accordance with my invention. Fig. 2. is a sectional view thereof, taken on the line 2 2 of Fig. 3. Fig. 3 is'a transverse section taken on the line 3 3 of Fig. 2. Fig. 4 is a sectional view taken on the line 4 4 of Fig. 3; and Fig. 5 is a similar section taken on the line 5 5 of Fig. 3. Fig. 6 is a detail View. I

In the said drawings, A represents the casing of my improved rotary engine, and B the flange thereof, suitably mounted on the base 0. The casin g A is provided with the steam inlet D on one side thereof and with the exhaust E on the other side thereof. The two are separated by means of the projections, hereinafter referred to, and thepiston which revolves within the casing, as will be more fully explained. The interior of the casing is provided with a number of projections F, which form the steam-spaces G and the exhaust-spaces H. They are arranged alternately, as shown in Fig. 2, and the steampassages are in communication with one side of the casing, while the exhaust-passages are in communication with the other. The advantage of having the four steam-spaces arranged at equidistant points is that the strain on the piston is distributed and a greater speed is obtained. The advantage of the four exhausts is that the steam-pockets of the piston are quickly emptied of steam, so that there will be little or no'resistance.

I represents the piston, formed of the side flanges I and the inclined blades 1 It is located centrally in the casing, so as to form a space on either side thereof, and it is secured on the shaft J by means of the flange J and bolts J {which pass through the flange J and a flange K on the shaft J. The shaft passes through the casing, and at those points the stuffing boxes L are provided,and its ends are journaled in the standards at the top of the standards M. The boxings M are so arranged that the joint between the cap-plate and the stationary part is not in line with the pull of the belt, so that the strain on these parts is to a great extent avoided.

As seen from the drawings, the piston pro-' jections F and the ends F of the steam and exhaust spaces prevent the live and exhaust steam intermingling, so that the live steam will enter the pockets of the piston and per 'form work and then escape through the ex haust-spaces into the exhaust side of the casing.

The operation of my device will be readily o understood. The steam enters the casing on one'side of the piston and passes into the steam-spaces and into the pockets of the pis-' ton to rotate it. As the pockets of the piston pass the exhaust-spaces the steam escapes 5 .into them and passes out on the other side of the piston through the exhaust D.

From the foregoing it will be seen that I have produced a rotary engine which, owing to its simplicity and increased number of [O0 steam inlet and outlet passages, will run at an increased speed.

It will be understood that I do not limit myself to the precise number of steam inlet and outlet passages nor to the exact arrangement of piston, as there could be a greater or less number and slightly-different arrangement of piston Without departing from the spirit of my invention. I also preferably have the side plates of the casing removable, so that the interior of the engine can be easily seen.

On each side of the piston-head is a plate or head N, secured thereto by bolt 0, said head or plate extending beyond the circumference of the piston-head and bolted to the parts F between the live-steam and exhaust openings of the cylinder. These heads are notched, one of them to conform to or register with the live-steam openings and the other to the exhaust-openings, and have suitable stuffing-boxes around the shafts.

Having thus fully described my invention, what I claim as new, anddesire to. secure by Letters Patent, is

1. In a rotary engine the combination with the driving-shaft,ofapiston suitably mounted thereon provided with a series of tangential blades forming pockets between them, an outer casin g provided with an interior annular projection adapted to fit against theperiphery of said piston, a series of spaces or pockets provided in the said annular projection and communicating with the pistonpockets and alternately communicating with the inlet and outlet chambers respectively, substantially as described.

2. The combination with the driving-shaft provided with an annular flange, of a piston provided with an annular flange adapted to be secured to the said driving-shaft flange, a series of tangential blades formed in the said piston, a casing provided with an annular projection adapted to fit against the periphery of said piston, a series of spaces or pockets provided in said annular projection communicating with the piston-pockets and alternately communicating with the' inlet and outlet chambers respectively, and a pair of circular disks provided on the sides of the piston-head extending beyond the circumference of said piston-head and bolted to the annular projection of the casing, substantially as described.

3. The combination with the driving-shaft of a rotary engine, of a casing suitably mounted thereon, an inlet and outlet chamber provided in said casing, a rotary piston detachablyconnect-edto said driving-shaft, a series of tangential blades provided in said piston, and a series of spaces or pockets provided in the said casing communicating with the piston-pockets and alternately communicating with the inlet and outlet chambers respectively, substantially as described.
